                                    PART I

ITEM 1.     BUSINESS

Introduction

     The Company is a leading manufacturer of copper, brass, plastic, and
aluminum products.  The range of these products is broad:  copper tube and
fittings; brass and copper alloy rod, bar, and shapes; aluminum and brass
forgings; aluminum and copper impact extrusions; plastic fittings and
valves; refrigeration valves and fittings; and fabricated tubular products.
Mueller's plants are located throughout the United States, and in Canada,
France, and Great Britain.  The Company also owns a short line railroad in
Utah.

     The Company's businesses are managed and organized into three
segments: (i) Standard Products Division ("SPD"); (ii) Industrial Products
Division ("IPD"); and (iii) Other Businesses.  SPD manufactures and sells
copper tube, copper and plastic fittings, and valves.  Outside of the
United States, SPD manufactures copper tube in Europe and copper fittings
in Canada.  SPD sells these products to wholesalers in the HVAC (heating,
ventilation, and air-conditioning), plumbing, and refrigeration markets,
and to distributors to the manufactured housing and recreational vehicle
industries.  IPD manufactures and sells brass and copper alloy rod, bar,
and shapes; aluminum and brass forgings; aluminum and copper impact
extrusions; refrigeration valves and fittings; fabricated tubular products;
and gas valves and assemblies.  IPD sells its products primarily to
original equipment manufacturers ("OEMs"), many of which are in the HVAC,
plumbing, and refrigeration markets.  Other Businesses include Utah Railway
Company and other natural resource properties and interests.  SPD and IPD
account for more than 98 percent of consolidated net sales and more than 86
percent of consolidated total assets.  The majority of the Company's
manufacturing facilities operated at high levels during 2000, 1999, and
1998.

     Information concerning segments appears under "Note 13 - Industry
Segments" in the Notes to Consolidated Financial Statements in Mueller's
Annual Report to Stockholders for the year ended December 30, 2000.  Such
information is incorporated herein by reference.

Standard Products Division

     Mueller's Standard Products Division includes a broad line of copper
tube, which ranges in size from 1/8 inch to 8 inch diameter, and is sold in
various straight lengths and coils.  Mueller is a market leader in the air-
conditioning and refrigeration tube markets.  Additionally, Mueller
supplies a variety of water tube in straight lengths and coils used for
plumbing applications in virtually every type of construction project.

     SPD also includes copper and plastic fittings and related components
for the plumbing and heating industry that are used in water distribution
systems, heating systems, air-conditioning, and refrigeration applications,
and drainage, waste, and vent systems.  A major portion of Mueller's
products are ultimately used in the domestic residential and commercial
construction markets and, to a lesser extent, in the automotive and heavy
on and off-the-road vehicle markets.


                                      -3-

     During the fourth quarter of 1998, the Company acquired Halstead
Industries, Inc. ("Halstead").  Halstead operates a tube mill in Wynne,
Arkansas, and a line sets factory in Clinton, Tennessee.  This acquisition
expanded the Company's copper tube and line sets businesses and created
opportunities for improved production and distribution efficiency.
Following the acquisition, Halstead's name was changed to Mueller Copper
Tube Products, Inc.  In addition, in August 1998, the Company acquired B&K
Industries, Inc. ("B&K"), an importer and distributor of residential and
commercial plumbing products.  The acquisition of B&K facilitated the sale
of Mueller's manufactured products in the large, and growing, retail
marketplace.  In 1997, the Company acquired copper tube manufacturing
operations in England and France.  These acquisitions established a
significant manufacturing and sales presence in Europe for the Company's
operations.

     SPD markets primarily through its own sales and distribution
organization, which maintains sales offices and distribution centers
throughout the United States and in Canada, Mexico, Great Britain, and
France.  Additionally, products are sold and marketed through a network of
agents, which, when combined with the Company's sales organization, provide
the Company broad geographic market representation.

     The businesses in which SPD is engaged are highly competitive.  The
principal methods of competition for Mueller's products are customer
service, availability, and price.  The total amount of order backlog for SPD
as of December 30, 2000 was not significant.

     The Company competes with various companies depending on the product
line.  In the U.S. copper tubing business, the domestic competition
includes Cerro Copper Products Co., Inc., Reading Tube Corporation, and
Wolverine Tube, Inc., as well as many actual and potential foreign
competitors. In the European copper tubing business, Mueller competes with
more than ten European-based manufacturers of copper tubing as well as
foreign-based manufacturers.  Additionally, the Company's copper tube
businesses compete with a large number of manufacturers of substitute
products made from plastic, iron, and steel.  In the copper fittings
market, competitors include Elkhart Products, a division of Amcast
Industrial Corporation, and NIBCO, Inc., as well as several foreign
manufacturers.  The plastic fittings competitors include NIBCO, Inc.,
Charlotte Pipe & Foundry, and other companies.  No single competitor offers
such a wide-ranging product line; management believes that this is a
competitive advantage in some markets.

Industrial Products Division

     Mueller's Industrial Products Division includes brass rod, nonferrous
forgings, and impact extrusions that are sold primarily to OEMs in the
plumbing, refrigeration, fluid power, and automotive industries, as well as
to other manufacturers and distributors.  The Port Huron, Michigan mill
extrudes brass, bronze, and copper alloy rod in sizes ranging from 3/8
inches to 4 inches in diameter.  These alloys are used in applications that
require a high degree of machinability, wear and corrosion resistance, and
electrical conductivity.  IPD also manufactures brass and aluminum forgings
which are used in a wide variety of end products, including automotive




                                      -4-

components, brass fittings, industrial machinery, valve bodies, gear
blanks, and computer hardware.  The Company also serves the automotive,
military ordnance, aerospace, and general manufacturing industries with
cold-formed aluminum and copper impact extrusions.  Typical applications
for impacts are high strength ordnance, high-conductivity electrical
components, builders' hardware, hydraulic systems, automotive parts, and
other uses where toughness must be combined with varying complexities of
design and finish.  Other products include valves and custom OEM products
for refrigeration and air-conditioning applications, and shaped and formed
tube, produced to tight tolerances, for baseboard heating, appliances,
medical instruments, etc.  The total amount of order backlog for IPD as of
December 30, 2000 was not significant.

     During 2000, the Company completed two acquisitions: (i) Micro Gauge,
Inc. and a related business, Microgauge Machining, Inc., a specialized
machining operation and (ii) Propipe Technologies, Inc., a fabricator of
gas train manifold systems.

     In September 1998, the Company acquired Lincoln Brass Works, Inc.
("Lincoln"), which operates manufacturing facilities in Jacksboro,
Tennessee and Waynesboro, Tennessee.  Lincoln produces custom control valve
assemblies, custom metal assemblies, gas delivery systems and tubular
products primarily for the gas appliance market.  Lincoln is a large
consumer of the Company's brass rod and forgings.

     IPD primarily sells directly to OEM customers. Competitors, primarily
in the brass rod market, include Cerro Metal Products Company, Inc., Chase
Industries, Inc., Extruded Metals Inc., and others both domestic and
foreign.  Outside of North America, IPD sells products through various
channels.

Other Businesses

     Mueller, through its subsidiary Arava Natural Resources Company, Inc.
("Arava"), is engaged in the operation of a short line railroad in Utah.
It also owns interests in other natural resource properties.

     Short Line Railroad

     Utah Railway Company ("Utah Railway"), a wholly-owned subsidiary of
Arava, operates on approximately 100 miles of railroad track in Utah.  Utah
Railway serves four major customers pursuant to long-term contracts which
account for more than 75 percent of coal tonnage hauled.  Utah Railway
transports coal to an interchange point at Provo, Utah. Although annual
tonnage may vary significantly due to fluctuations in the production from
the coal mines on the Utah Railway's lines and the demand for export coal,
in recent years, annual tonnage has ranged between four and six million
tons.  From Provo, Utah, the coal is transported by connecting railroads to
various customers including electric utilities, cement plants, west coast
export facilities and others at destinations throughout the West.

     In late 1998, there was a fire at one of the coal mines served by Utah
Railway.  The mine reopened in late 1999, and its shipments on Utah Railway
resumed through July 2000.  A second fire occurred at this same mine in
August 2000.  The future production from this mine is uncertain.



                                      -5-

     On September 30, 1999, Utah Railway purchased the stock of the Salt
Lake City Southern Railroad Company, Inc. ("SLCS").  SLCS operates pursuant
to an easement on approximately 25 miles of track, owned by the Utah
Transit Authority, from downtown Salt Lake City to near Draper, Utah.

     In addition to railway operations discussed above, Union Pacific
Railroad granted limited rights to Utah Railway for operations over Union
Pacific tracks to Grand Junction, Colorado and access to additional coal
customers.  Also, Utah Railway conducts switching operations primarily in
the Salt Lake City, Ogden, and Provo, Utah, metropolitan areas.  Switching
operations consist of accepting freight from other railroad carriers for
delivery to customers and/or accepting loads of freight from such customers
for delivery to long haul railroad carriers to be transported to final
destinations.

     Other Properties

     In early 1998, Ruby Hill Mining Company ("Ruby Hill") received a final
$1.0 million installment payment from Homestake Mining Company of
California ("Homestake") for Ruby Hill's mining property near Eureka,
Nevada.  Prior to 1999, the Company received and recognized as gains $4.0
million from this transaction.  If Homestake produces a total of 500,000
ounces of gold or "gold equivalents" of other metals from this property,
Ruby Hill is thereafter entitled to a three percent net smelter return
royalty, after deduction for certain taxes and transportation.

Labor Relations

     At December 30, 2000, the Company employed approximately 4,300
employees of which approximately 1,700 were represented by various unions.
Union contracts at the Company's European operations are renewed annually.
Other contracts expire on various dates through April 2004.


Raw Material and Energy Availability

     The major portion of Mueller's base metal requirements (primarily
copper) is normally obtained through short-term supply contracts with
competitive pricing provisions (for cathode) and the open market (for
scrap).  Other raw materials used in the production of brass, including
brass scrap, zinc, tin, and lead, are obtained from zinc and lead
producers, open-market dealers, and customers with brass process scrap.
Raw materials used in the fabrication of aluminum and plastic products are
purchased in the open market from major producers.

     Adequate supplies of raw material are available to the Company.
Sufficient energy in the form of natural gas, fuel oils, and electricity is
available to operate the Company's production facilities.  While temporary
shortages of raw material and fuels may occur occasionally, they have not
materially hampered the Company's operations.

Environmental Matters

     Compliance with environmental laws and regulations is a matter of high
priority.  Mueller's provision for environmental compliance includes
charges of $2.0 million in 2000 and $2.1 million in 1998.  There was no
provision for 1999.   Except as discussed below, the Company does not

                                      -6-

anticipate that it will need to make material expenditures for such
compliance activities during the remainder of the 2001 fiscal year, or for
the next two fiscal years.

     In 1998 and 1997, in connection with acquisitions, the Company
established environmental reserves to fund the cost of remediation at sites
currently or formerly owned by various acquired entities.  The Company,
through its acquired subsidiaries, is engaged in ongoing remediation and
site characterization studies.

     Mining Remedial Recovery Company ("MRRC"), a wholly-owned subsidiary
of Arava, was formed for the purpose of managing the remediation of certain
properties and the appropriate disposition thereof.

     1. Mammoth Mine Site

     MRRC owns title to certain inactive mines in Shasta County,
California.  MRRC has continued a program, begun in the late 1980s, of
sealing mine portals with concrete plugs in mine adits which were
discharging water.  The sealing program has achieved a reduction in the
metal load in discharges from these adits; however, additional reductions
are being required.  In response to a 1996 Order issued by the California
Regional Water Quality Control Board ("QCB"), MRRC completed a feasibility
study in 1997 describing measures designed to mitigate the effects of acid
rock drainage.  In December 1998, the QCB issued a new order extending
MRRC's time to comply with water quality standards until December 1, 2003.
MRRC agreed to continue remedial activities to reduce or prevent discharge
of acid mine drainage and submitted to the QCB in July 2000 a Use
Attainability Analysis ("UAA"), which is under review.  MRRC estimates it
will spend between $1.0 and $2.0 million on planned remedial activities.
Further remediation may be required depending on QCB's acceptance of the
UAA and how effective MRRC's remedial options are in reducing acid rock
drainage.

     2. U.S.S. Lead

     In 1991, U.S.S. Lead Refinery, Inc. ("Lead Refinery"), responded to
an information request from the EPA under Superfund for information on
whether Lead Refinery arranged for the disposal of hazardous substances in
the vicinity of the Grand Calumet River/Indiana Harbor Ship Canal.  By
letter dated February 4, 1997, the Indiana Department of Environmental
Management ("IDEM") notified Lead Refinery that a preassessment screening
of the Grand Calumet River and the Indiana Harbor Canal conducted pursuant
to Superfund had identified releases of hazardous substances from Lead
Refinery and other potentially responsible parties ("PRPs") that had
adversely impacted natural resources.  Based on its prescreening work, IDEM
performed sampling in this area and initiated an assessment plan, which
will determine the nature and extent of any required remediation and any
resulting assessments against any of the PRPs.

     In 1991, Lead Refinery also responded to an information request under
Superfund regarding the site in East Chicago, Indiana.  In 1992, the EPA
advised Lead Refinery of its intent to list the property as a Superfund
site; however, as of March 23, 2001, the EPA has deferred such listing.  In
1993, Lead Refinery entered into a Consent Order with the EPA pursuant to
Section 3008(h) of the Resource Conservation and Recovery Act ("RCRA").


                                      -7-

The consent Order covers remediation activities at the East Chicago,
Indiana site and provides for Lead Refinery to complete certain on-site
interim remedial activities and studies that extend off-site.  In November
1996, the EPA approved, with modifications, the Interim Stabilization
Measures Workplan and designated a Corrective Action Management Unit
("CAMU") at the Lead Refinery site.  Site activities, which began in
December 1996, should be substantially concluded in 2001.  Costs for
remaining cleanup efforts are estimated to be between $1.0 and $2.0
million.  In the process of remediating the site, Lead Refinery identified
petroleum contamination on site.  As a result, Lead Refinery installed a
slurry wall around the CAMU and initiated characterization of areas
suspected to have petroleum contamination.  Lead Refinery has addressed
this contamination pursuant to plans approved by the EPA.  Additionally,
Lead Refinery has conducted initial investigations to determine if other
contamination exists that is not addressed by the Consent Order.  Lead
Refinery, without additional assistance from MRRC, lacks the financial
resources needed to complete any additional remediation determined to be
required and intends to seek financial assistance from other PRPs to permit
Lead Refinery to conduct a private-party cleanup under RCRA, to the extent
available under applicable law and regulations.

     Lead Refinery has been informed by the former owner and operator of a
Superfund site located in Pedricktown, New Jersey that it intends to seek
CERCLA response costs for alleged shipments of hazardous substances to the
site.  Lead Refinery has executed an agreement regarding that site, which
indefinitely extends the statute of limitations.  By letter dated January
26, 1996, Lead Refinery and other PRPs received from the EPA a proposed
Administrative Order on Consent to perform the remedial design for operable
Unit 1 of the Pedricktown Superfund Site.  Lead Refinery determined not to
execute the Administrative Order on Consent.  Several other PRPs, however,
executed the agreement and are conducting the remedial design.

     3. Mueller Copper Tube Products, Inc.

     In 1999, Mueller Copper Tube Products, Inc. ("MCTP"), commenced a
cleanup and remediation of soil and groundwater at its Wynne, Arkansas
plant.  MCTP is currently removing trichloroethene, a cleaning solvent
formerly used by MCTP, from the soil and groundwater.  On August 30, 2000,
MCTP received approval of its Final Comprehensive Investigation report and
Storm Water Drainage Investigation Report addressing the treatment of soils
and groundwater, from the Arkansas Department of Environmental Quality.
The Company anticipates that MCTP will spend up to an estimated five million
dollars over the next several years on these activities and established a
reserve for this project in connection with the acquisition of MCTP.

Other Business Factors

     The Registrant's business is not materially dependent on patents,
trademarks, licenses, franchises, or concessions held.  In addition,
expenditures for company-sponsored research and development activities were
not material during 2000, 1999, or 1998.  No material portion of the
Registrant's business involves governmental contracts.
